Slowness issue while applying sequence water mark to video

[Jay-154]

I am able to add a sequence watermark to the bbb-short.mp4 video from the examples/videos folder, but it takes around two minutes to complete the process. Especially the encode_async method is taking time to complete the process.
In order to speed up the process, could someone please assist me with this issue. I'm currently applying the watermark on a video by using the below command .

bvw embed -a seq -wm 2012 -i bbb-short.mp4 -o output.mp4 -k 123 456 789 -j 4
